HPCL's Mumbai Refinery at Mahul, Chembur is one of India's most strategically significant and technically complex refining facilities — a 9.5 MMTPA integrated fuels and lubricants complex that traces its origins to 1954, when Esso Standard commissioned it as India's first modern refinery, and which has been continuously expanded and upgraded across seven decades since its nationalisation into HPCL in 1974.

Operating with a high Nelson Complexity Index underpinned by two FCCUs, a CLG ISOCRACKING hydrocracker, catalytic reforming, isomerisation, gasoline desulphurisation (Axens Prime-G+), diesel hydrotreating, and a propylene recovery unit producing 100,000 TPA of chemical-grade propylene, the refinery delivers a full BS-VI compliant fuels slate to India's largest metropolitan market.

What truly distinguishes it, however, is its integrated Lube Refinery — India's largest, tracing its own lineage to the 1969 Lube India Limited joint venture — which currently produces 475,000 TPA of Group II/II+ lube base stocks across over 300 grades, and is undergoing a ₹4,679 crore (~USD 500 million) modernisation that will expand LOBS capacity to 764,000 TPA of premium Group II+ and Group III base oils by 2028, anchored by a new CLG ISOCRACKING + ISODEWAXING integrated hydrocracker and a KBR ROSE® solvent deasphalting unit — cementing Mumbai's position as the nerve centre of India's lubricants industry.
